Salifert Test Kits

I just replaced pretty much all of my test kits with Salifert test kits. I had a bunch of different brands in the past, and they were getting old so it was time to replace them. I'll tell you, the salifert kits are not inexpensive when you buy a whole bunch of them at once, but the quality is great. Very clear, and easy titrations, very obvious color gradiations, etc. I highly suggest using these kits..at least the ones I have had experience with so far (Mg, Ca, PH, KH/ALK, Nitrate).

 

you would prob need phosphate 2.

 

Yes, they aren't exactly cheap hehe. Make sure you shop around a little bit too, some places have much better prices than others which might help a bit.
They are also good quality kits IMO as well, glad you got some good test kits!
